Manchester City legend and former director Dennis Tueart believes City need to sell Carlos Tevez in order to make room for Robin van Persie.
But Tueart said he felt City boss Roberto Mancini would be better off buying defender Daniel Agger and midfielder Daniele De Rossi than adding another striker to his ranks.
He said: "From my observations of City, they need to buy two players who complement the team ethic and will give the team balance and shape, rather than just individuals, and that is always the biggest challenge.
"I felt that City's big problem was that last season they didn't have two strikers who could be a pairing. Instead, they were all single frontmen. Aguero was a fantastic acquisition, one of the best players in the Premier League, and if you do bring in Van Persie, then for me Tevez would be the one to go - and because of his personality, you might always end up with trouble with him.
"But I am not sure Van Persie would resolve the pairing issue, and at the age of 29 and for his games per season ratio - which is poor, apart from last season - I am not sure he represents value for money. I think Arsene Wenger won't be unhappy if he keeps Van Persie, and the Arsenal system suits him.
"City need De Rossi in midfield and a top left-sided central defender, because Kompany was fantastic, Lescott was very good and it was then the best of the rest - so a top-quality player in that position would be the priority for me, as well as left-sided midfield."
Tueart said he believed City would "have a great chance again this season", but warned that much would depend on who they were able to buy.
